    986    - Major revision release: should be API and ABI compatible but got a lot
    987     of change
    988    - Increased the library modularity, far more options can be stripped out,
    989     a --with-minimum configuration will weight around 160KBytes
    990    - Use per parser and per document dictionnary, allocate names and small
    991     text nodes from the dictionnary
    992    - Switch to a SAX2 like parser rewrote most of the XML parser core,
    993     provides namespace resolution and defaulted attributes, minimize memory

   1807    - 1.8.8 is mostly a commodity package for upgrading to libxml2 according
   1808     to new instructions. It fixes a nasty problem
   1809     about &#38; charref parsing
   1810    - 2.1.0 also ease the upgrade from libxml v1 to the recent version. it
   1811     also contains numerous fixes and enhancements:
   1812     added xmlStopParser() to stop parsing

   1823    - tried to fix as much as possible DTD validation and namespace
   1824         related problems
   1825    - output to a given encoding has been added/tested
   1826    - lot of various fixes
   1827 
   1828 
   1829 2.0.0: Apr 12 2000:
   1830    - First public release of libxml2. If you are using libxml, it's a good
   1831     idea to check the 1.x to 2.x upgrade instructions. NOTE: while initially
   1832     scheduled for Apr 3 the release occurred only on Apr 12 due to massive
   1833     workload.
   1834    - The include are now located under $prefix/include/libxml (instead of
   1835     $prefix/include/gnome-xml), they also are referenced by
   1836     #include <libxml/xxx.h>
   1837     instead of
   1838     #include "xxx.h"
   1839   
   1840    - a new URI module for parsing URIs and following strictly RFC 2396
   1841    - the memory allocation routines used by libxml can now be overloaded
   1842     dynamically by using xmlMemSetup()
   1843    - The previously CVS only tool tester has been renamed
   1844     xmllint and is now installed as part of the libxml2
   1845     package
   1846    - The I/O interface has been revamped. There is now ways to plug in
   1847     specific I/O modules, either at the URI scheme detection level using
   1848     xmlRegisterInputCallbacks()  or by passing I/O functions when creating a
   1849     parser context using xmlCreateIOParserCtxt()
   1850    - there is a C preprocessor macro LIBXML_VERSION providing the version
   1851     number of the libxml module in use
   1852    - a number of optional features of libxml can now be excluded at
   1853     configure time (FTP/HTTP/HTML/XPath/Debug)
   1854 
   1855 
   1856 2.0.0beta: Mar 14 2000:
   1857    - This is a first Beta release of libxml version 2
   1858    - It's available only fromxmlsoft.org
   1859     FTP, it's packaged as libxml2-2.0.0beta and available as tar and
   1860   RPMs
   1861    - This version is now the head in the Gnome CVS base, the old one is
   1862     available under the tag LIB_XML_1_X
   1863    - This includes a very large set of changes. From a  programmatic point
   1864     of view applications should not have to be modified too much, check the
   1865     upgrade page
   1866    - Some interfaces may changes (especially a bit about encoding).
   1867    - the updates includes:
   1868     fix I18N support. ISO-Latin-x/UTF-8/UTF-16 (nearly) seems correctly
   1869         handled now
   1870       Better handling of entities, especially well-formedness checking
   1871         and proper PEref extensions in external subsets
   1872       DTD conditional sections
   1873       Validation now correctly handle entities content
   1874       change
   1875         structures to accommodate DOM
   1876     
   1877    - fix I18N support. ISO-Latin-x/UTF-8/UTF-16 (nearly) seems correctly
   1878         handled now
   1879    - Better handling of entities, especially well-formedness checking
   1880         and proper PEref extensions in external subsets

   1882    - Validation now correctly handle entities content
   1883    - change
   1884         structures to accommodate DOM
   1885    - Serious progress were made toward compliance, here are the result of the test against the
   1886     OASIS testsuite (except the Japanese tests since I don't support that
   1887     encoding yet). This URL is rebuilt every couple of hours using the CVS
   1888     head version.
   1889 
   1890 
   1891 1.8.7: Mar 6 2000:
   1892    - This is a bug fix release:
   1893    - It is possible to disable the ignorable blanks heuristic used by
   1894     libxml-1.x, a new function  xmlKeepBlanksDefault(0) will allow this. Note
   1895     that for adherence to XML spec, this behaviour will be disabled by
   1896     default in 2.x . The same function will allow to keep compatibility for
   1897     old code.
   1898    - Blanks in <a>  </a> constructs are not ignored anymore,
   1899     avoiding heuristic is really the Right Way :-\
   1900    - The unchecked use of snprintf which was breaking libxml-1.8.6
   1901     compilation on some platforms has been fixed
   1902    - nanoftp.c nanohttp.c: Fixed '#' and '?' stripping when processing
   1903   URIs

   1908     it without troubles
   1909 
   1910 
   1911 1.8.5: Jan 21 2000:
   1912    - adding APIs to parse a well balanced chunk of XML (production [43] content of the
   1913     XML spec)
   1914    - fixed a hideous bug in xmlGetProp pointed by Rune.Djurhuus (a] fast.no
   1915    - Jody Goldberg <jgoldberg (a] home.com> provided another patch trying
   1916     to solve the zlib checks problems
   1917    - The current state in gnome CVS base is expected to ship as 1.8.5 with
   1918     gnumeric soon
   1919 
   1920 
   1921 1.8.4: Jan 13 2000:
   1922    - bug fixes, reintroduced xmlNewGlobalNs(), fixed xmlNewNs()

   1936     xmlLoadExternalEntity(), some fix on entities processing were added
   1937    - cleaned up WIN32 includes of socket stuff
   1938 
   1939 
   1940 1.8.2: Dec 21 1999:
   1941    - I got another problem with includes and C++, I hope this issue is fixed
   1942     for good this time
   1943    - Added a few tree modification functions: xmlReplaceNode,
   1944     xmlAddPrevSibling, xmlAddNextSibling, xmlNodeSetName and
   1945     xmlDocSetRootElement
   1946    - Tried to improve the HTML output with help from Chris Lahey
   1947 
   1948 
   1949 1.8.1: Dec 18 1999:
   1950    - various patches to avoid troubles when using libxml with C++ compilers
   1951     the "namespace" keyword and C escaping in include files
   1952    - a problem in one of the core macros IS_CHAR was corrected
   1953    - fixed a bug introduced in 1.8.0 breaking default namespace processing,
   1954     and more specifically the Dia application
   1955    - fixed a posteriori validation (validation after parsing, or by using a
   1956     Dtd not specified in the original document)
   1957    - fixed a bug in
   1958 
   1959 
   1960 1.8.0: Dec 12 1999:
   1961    - cleanup, especially memory wise
   1962    - the parser should be more reliable, especially the HTML one, it should
   1963     not crash, whatever the input !
   1964    - Integrated various patches, especially a speedup improvement for large
   1965     dataset from Carl Nygard,
   1966     configure with --with-buffers to enable them.
   1967    - attribute normalization, oops should have been added long ago !
   1968    - attributes defaulted from DTDs should be available, xmlSetProp() now
   1969     does entities escaping by default.
   1970 
   1971 
   1972 1.7.4: Oct 25 1999:
   1973    - Lots of HTML improvement

   1979 1.7.3: Sep 29 1999:
   1980    - portability problems fixed
   1981    - snprintf was used unconditionally, leading to link problems on system
   1982     were it's not available, fixed
   1983 
   1984 
   1985 1.7.1: Sep 24 1999:
   1986    - The basic type for strings manipulated by libxml has been renamed in
   1987     1.7.1 from CHAR to xmlChar. The reason
   1988     is that CHAR was conflicting with a predefined type on Windows. However
   1989     on non WIN32 environment, compatibility is provided by the way of  a
   1990     #define .
   1991    - Changed another error : the use of a structure field called errno, and
   1992     leading to troubles on platforms where it's a macro
   1993 
   1994 
   1995 1.7.0: Sep 23 1999:

   1998     like callback
   1999    - Finished ID/IDREF support and checking when validation
   2000    - Serious memory leaks fixed (there is now a memory wrapper module)
   2001    - Improvement of XPath
   2002     implementation
   2003    - Added an HTML parser front-end
